Hi, I try to get rid of cleartext passwords stored in a MySQL db, and replace them by NT hashes. I set up a test environment and first tried with an entry in users:
swinter NT-Password := "...", Auth-Type := Accept
which worked okay.
Storing the same password in MySQL did NOT work, with a quite spurious error,
see below:
Nothing to do. Sleeping until we see a request.

Especially the lines

radius_xlat: ''
rlm_pap: mschap xlat failed
appear suspicious ("test" is the password"). Maybe there's some xlat escaping
wrong?
The configuration in use is almost as shipped, only added sql config.
